WILLIAM H. DAVENPORT, OF PROVIDENCE, RHODE ISLAND.

BREECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 243,223, dated June 21, 1881.

Application filed April 13, i881.

To all whom. it may concern Be it known that I, WILLIAM H. DAVEN- PORT, of Providence, in the State of Rhode Island, have made certain new and useful lm provementsinBreech-LoadingFire-Arms5 and I do hereby declare that the following specification,taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure l is a section through the breechpiece, showing the look mechanism. Fig. 2 is a view of the same, showing the thumb-snap upon the under side.

My improvements relate to what is known in the market as a hammerless7 gunthat is, one in which the hammer is located within the lock-frame; and it consists in the mechanism for cockin g the piece, locking the hammer at a full-cock, and subsequently releasing the same, as hereinafter described.

A, Figs. 1 and 2, is a section of the lockframe, which has a suitable interior chamber for the reception and operation of the lock mechanism.

B is a section of the barrel, which is hinged to the end of the frame A.

C is the hammer, which is located and works entirely within the lock-frame A.

D is the flringpin,E the main spring, F the trigger, and H the locking-bolt.

K is a thumb-lever projecting through a slot in the lock-frame A, either upon the top, as shown in Fig. l, or upon the under side, as shown in Fig. 2, as may be desired.

L is a link or bar connecting the thumb-lever K with the locking-bolt H. The link Lis pro vided upon its upper side with a projection, M, to which is attached a roller, N, which forces back the hammer C, and upon its under side with a lug or pin, O.

P is a locking-lever, which is brought into engagement with the trigger F by the lug O upon the under side of the link L, and releases the trigger F through the rod Q, lever R, and slide S upon the outside of the lockframe.

The operation of my invention is as follows: The thumb-lever K, being pivoted at its lower end, and having attached to it the link L, is

(No model.)

drawn back to the position indicated by dotted lines, Fig. 1. This operation draws hack the link L and the locking-bolt H. The linkL in its backward movement, through its projection M and roller N, comes in contact with and forces back the hammer C to a full-cock, and, through its lug O, forces the lever P into engagement with the trigger F and securely locks'the hammerin that position, as shown in Fig. 1. While the pressure is retained upon the thumb-lever K the barrel may be tipped to receive a cartridge and snapped back again to its former position. When the pressure is removed from the lever K it will, with the link L, drop back to the position shownin Fig. l. The piece may now be carried at a full-cock without the liability of accidental discharge.

When it is desired to discharge the gun the slide S is moved forward by the thumb or 1in ger, and, through the lever R and rod Q, moves back the locking-lever P and unlocks the trigger F, which, upon being pulled, releases the hammer O, which, by the action ofthe spring E, strikes the firing-pin T and discharges the piece. The operation of cooking, charging, and discharging may now be repeated, as before described.

To be able to readily see whether or not the piece is at4 a full-cock, I provide a signal-pin, U, extending through the lock-frame, the upper end of which is flush with the exterior surface of the lock-frame while the hammer is down, and is retained in that position by the spring V. When the piece is brought to a fullcock the hammer O comes in contact with the signal-pin U, and, overcoming the resistance of the spring V, raises it up and holds it with its upper end sufficiently projecting above the surface of the lock-frame to be readily seen and inform the carrier of the position of the hammer.

With the mechanism that I have described the piece may be brought from a' full to a half cock by first disengaging the lever P, as before described, when the gun is to be discharged, and then holding the hammerv back by the thumb-lever K and link L While the triggerF is thrown out from its shoulder, after which the thumb-lever K is gradually let forward until the trigger F catches in the halfcock notch upon the hammer C, where it may be again locked by the lever P.

The leverK may, if desired, be placed upon the under side, as shownin Fig. 2, and arranged 5 to operate in the manner before described.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the hammer C, the lever K, pivoted Within the lock, and havin g an 1o external projecting thumb-piece, the lockingbolt H, and the link L, connecting,` the lever Y K and bolt H, and provided With aprojection, M, and rollerN to engage beneath the neck of WM. H. DAVENPORT.
